Chihiro Himukai Always Walks Away

Years after they drifted apart, the narrator runs into Chihiro, a former classmate who has just walked out of yet another job. When she overhears his coworkers needling him, she proposes a no-strings arrangement on the spot, and the story begins at the point where most romances end.

What follows is less about the arrangement than about Chihiro herself: a kind, impulsive young woman whose strong sense of fairness keeps colliding with workplaces that do not share it. The narrator slowly works out why she runs, and both of them have to decide whether what they have is worth naming.

It is a compact, single-heroine story with full Japanese voice acting and an adult cast in ordinary city jobs. The Steam and GOG versions are all-ages; the publisher offers an official free patch that restores the adult scenes.
